Regression Notes

1. Potential unintended areas of impact

• Fixed site icon progress, did not find a case where it may misbehave.

2. What I did to test those areas of impact (or what existing automated tests I relied on)

• Manual tests

3. What automated tests I added (or what prevented me from doing so)

• Changes do not require extra tests nor do they affect existing.

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
